ocelot_regs.c actually shouldn't be part of the common library. It
describes the register map of the VSC7514 switch. The way ocelot
switches work, they'll have highly optimized register maps, so another
SoC will likely have the same registers but laid out completely
different in memory (so there's little room for reusing this structure).
So move it to ocelot_vsc7514.c instead.

When running 'bridge fdb dump' on Felix, sometimes learnt and static MAC
addresses would appear, sometimes they wouldn't.
Turns out, the MAC table has 4096 entries on VSC7514 (Ocelot) and 8192
entries on VSC9959 (Felix), so the existing code from the Ocelot common
library only dumped half of Felix's MAC table. They are both organized
as a 4-way set-associative TCAM, so we just need a single variable
indicating the correct number of rows.

The adjust_link routine should be generic enough to be (re)used by
any SoC that integrates a switch core compatible with the Ocelot
core switch driver. Currently all configurations are generic except
for the PCS settings that are SoC specific. Move these out to the
Ocelot SoC/board instance.

This patch adds support for using the PTP register range, and adds a
description of its registers. This bank is used when configuring PTP.

Add ACL support using the TCAM. Using ACL it is possible to create rules
in hardware to filter/redirect frames.

Previously, the SerDes muxing was hardcoded to a given mode in the MAC
controller driver. Now, the SerDes muxing is configured within the
Device Tree and is enforced in the MAC controller driver so we can have
a lot of different SerDes configurations.
Make use of the SerDes PHYs in the MAC controller to set up the SerDes
according to the SerDes<->switch port mapping and the communication mode
with the Ethernet PHY.

Since HSIO address space can be accessed by different drivers, let's
simplify the register address definitions so that it can be easily used
by all drivers and put the register address definition in the
include/soc/mscc/ocelot_hsio.h header file.

Add a driver for Microsemi Ocelot Ethernet switch support.
This makes two modules:
mscc_ocelot_common handles all the common features that doesn't depend on
how the switch is integrated in the SoC. Currently, it handles offloading
bridging to the hardware. ocelot_io.c handles register accesses. This is
unfortunately needed because the register layout is packed and then depends
on the number of ports available on the switch. The register definition
files are automatically generated.
ocelot_board handles the switch integration on the SoC and on the board.
Frame injection and extraction to/from the CPU port is currently done using
register accesses which is quite slow. DMA is possible but the port is not
able to absorb the whole switch bandwidth.
